This paper proposes a scheme for calculating aggregate values of data owned by anonymous entities. Linear mix-nets, an unknown unique number generator, and anonymous tag based credentials efficiently conceal not only identities of data owners but also linkages between data owned by same entities. Then, the scheme enables quick introduction of advancing information technologies to industrial applications while ensuring confidentiality of sensitive data, e.g. a machine maintenance company can monitor states of machines remotely without knowing secrets of machine owners, companies can outsource even their sensitive tasks without worrying about leaks of their secrets. The scheme is also applicable to tasks in e-governance systems such as tax-collections where privacies of individuals must be preserved.

The Modular Multi-level Converter (M2LC) topology promises to outperform other known converter topologies in various medium to high voltage applications. The topology requires a control scheme for controlling the voltage across module capacitors. This paper proposes a variant of the M2LC topology, which is based on Inductive Power Transfer (IPT) technology, to maintain the capacitor voltages within tight bounds. The proposed M2LC-IPT topology has the unique ability of independent control of capacitor voltages and load currents, and is even capable of producing a regulated output at low output frequency. To validate the proposed concept, simulated performance of a three-phase, three-level grid connected 2 kVA M2LC-IPT is presented with a discussion. A comparison with a conventional topology is also carried-out to demonstrate the improvements in performance associated with the M2LC-IPT.

The aim of this paper is to identify and analyze the impact of a design change in a concurrent systems engineering environment. A mathematical model has been developed to quantify the impact of a design change on a multi-layer, multi-component system. This model confirms that the system hierarchy design is very important to minimize the impact and subsequent development project risk should a design change be required for one of the system components. The mathematical model shows that a design change often has a detrimental effect on project cost and schedule due to the ripple effect of forced design changes to all other functionally coupled system elements. In practice, design modifications/changes particularly during system integration of a complex multi-hierarchical system are virtually unavoidable. The impact of forced changes can only be improved by optimizing the system architecture to keep the system data content or functional couplings to a minimum. The actual impact of a design change in a real system under development can by means of the model be calculated in order to assess the feasibility of allowing the design change or to rather look for alternative lesser development project intrusive solutions to the problem at hand. The model shows that early system engineering to optimize the system architecture with the objective of reducing the system information content is beneficial. This will reduce development project risk as result of unexpected forced design changes in a concurrent engineering development environment. The paper shows that in order to reduce system development project risk, it is important to minimise the system data content (functional couplings) and mature each system element design before integration.

In the real world, the adoption of information technology (IT) innovations is a complex process involving three main entities: (i) promoters, who facilitate the adoption process, (ii) inhibitors, who oppose the adoption of technology, and (iii) imitators who are influenced by both promoters and inhibitors. In the presence of promoters and inhibitors, managing technology innovation and adoption is a complex task. Since most of the IT innovations are characterized by these actors, understanding the dynamics of their diffusion and adoption is imperative. This research seeks to develop a system dynamics model to capture the interactive dynamics of IT adoption in a complex environment involving promoters, inhibitors, and imitators. Based on a set of experiments, we investigate via simulation, the behavior of a typical diffusion and adoption process, drawing useful managerial implications for technology policy makers. What-if analyses experiments are carried out in order to obtain further insights into policy design and evaluation for effective technology management.

Research has revealed that the correlation between distance and RSSI (Received Signal Strength Indication) values is the key of ranging and localization technologies in wireless sensor networks (WSNs). In this paper, an RSSI model that estimates the distance between sensor nodes in WSNs is presented. The performance of this model is evaluated and analyzed in a real system deployment in an indoor and outdoor environment by performing an empirical measurement using Crossbow IRIS wireless sensor motes. Our result shows that there is less error in distance estimation in an outdoor environment compared to indoor environment. The results of these evaluations would contribute towards obtaining accurate locations of wireless sensor nodes.

State of Charge (SoC) imbalance between battery modules is unavoidable in high capacity Battery Energy Storage Systems (BESS). This paper investigates a module level SoC balancing control in cascaded H-bridge inverter (CHB) based BESS using multi-dimensional modulation technique. Multi-dimensional modulation is a generalized modulation strategy for cascaded H-bridge inverters. With the proposed control strategy, SoC can be equalized between the battery modules in a phase leg of CHB. The performance of the proposed control strategy under faulty cell operation is also studied. The multi-dimensional modulation strategy and the SoC balancing control are explained and the simulation results are given in this paper.

This paper discusses the control of an AC-to-AC converter that forms part of an 11 kV electronic voltage regulator. A novel finite-set model predictive control technique is presented to allow fixed frequency switching. A fixed switching period is defined and divided into smaller evaluation steps. The switching behaviour is obtained by using the analogy of PWM with a triangular carrier wave. During the first half of the switching period, the system may only switch from the on-state to the off-state and during the second half, only from the off-state to the on-state. To account for the repetitive nature of the switching waveform, an average receding horizon prediction method is introduced. An anticipated prediction is made by calculating the average value for one switching period ahead, according to the position and state in the current switching period. The method presented good practical results and proved to be effective in maintaining a fixed switching frequency.

In this paper, we try to present a sliding mode with fuzzy-neural network controller for nonlinear systems. It is a special nonlinear control method (SMC) which has quick response, insensitive to parameters variation and disturbance. Online identification for plants is not needed, it's very suitable for nonlinear system control, but in reality using the chattering reduction and elimination are key problem in SMC. By using a function-augmented sliding hyper plane, it is guaranteed that the output tracking error converges to zero in finite time which can be set arbitrarily. The fuzzy-neural network mainly Self Tuning Fuzzy Inference System (STFIS) is used to approximate the unknown system functions and switch item. Finally, the sliding-mode with fuzzy-neural network control is used to control single inverted pendulum and confirms the validity of the proposals. Results of simulations containing tests of robustness are presented and realized in MATLAB environment.

In this paper, a p-q theory based approach, using Complex Notch Filter, is proposed to control active and reactive power flow of a distributed generator connected to a generalized unbalanced grid. The proposed method facilitates high bandwidth grid power flow control along with maintaining sinusoidal grid currents by finding suitable inverter current references directly in the a-b-c frame. The proposed method is faster than the conventional methods because of the absence of the Phase Lock Loop and Park's transformation requirement. A novel method of extracting the phase angle of the fundamental grid voltage is proposed. A Complex Notch Filter based method for extracting positive and negative sequence components together with filtering grid voltage harmonics is also proposed to reduce the computational burden on the processor. The method is devised for a generalized three-phase system. The proposed method is validated through rigorous tests and experimental results presented depict the efficacy of the proposed method.

The pressure of increasing power demand and supply inequality is forcing utilities to interconnect AC systems to meet demands. High Voltage Direct Current (HVDC) schemes are becoming a more attractive solution as they have been used extensively in interconnected power systems worldwide. This paper investigates the role of voltage source converter (VSC) based HVDC transmission corridor for PV power injection and for AC network stability support. Overview of Namibia Caprivi-link interconnector a case study, potential of very large scale PV in Namibia and prospects of PV power injection on the DC-link is presented. The system is modelled simulated in Matlab/Simulink. Critical contingencies such as sudden island conditions, three-phase to ground fault are simulated with and without PV penetration. Results show the stability support on the AC side networks by PV power injection on the dc-link.
